Description

Technical Field

[0001] This utility model relates to the field of environmental protection and dust removal technology, and in particular to a high-efficiency vibrating bag filter. Background Technology

[0002] With the acceleration of industrialization, factories and other industrial production processes generate a large amount of dust-laden gas. If this gas is discharged directly into the atmosphere without treatment, the dust particles will pollute the air, affect air quality, and cause environmental problems such as smog. Baghouse dust collectors can efficiently capture particulate matter in these dust-laden gases and discharge the purified, relatively clean gas, effectively reducing the concentration of air pollutants and mitigating damage to the ecological environment.

[0003] After filtering dust for a long time, existing filter bags tend to accumulate dust on their surface, causing caking. This results in poor air permeability and a sharp drop in dust removal efficiency, requiring frequent cleaning, which is extremely inconvenient. Utility Model Content

[0004] The purpose of this utility model is to solve the following shortcomings in the prior art: after filtering dust for a long time, the dust in the existing filter bags tends to adhere to the surface of the filter bags and form a caking phenomenon, which leads to poor air permeability of the filter bags and a sharp drop in dust removal efficiency. Therefore, the filter bags need to be cleaned frequently, which is extremely inconvenient. Therefore, a high-efficiency vibrating filter bag dust collector is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-efficiency vibrating bag filter includes a body, in which a filter bag is fixedly installed on the top wall. The surface of the body has multiple circumferentially open and closed openings. Insert rods are slidably inserted into the openings. One end of the insert rod is fixedly installed with a vibrating ball via a connecting rod, and the other end is fixedly installed with a vertical plate. An inclined plate is fixedly installed at the top of the vertical plate. A reciprocating screw is vertically fixedly installed on the upper surface of the body. A movable ring is threaded onto the reciprocating screw. The movable ring is restricted from rotation by a limiting component. The rotation of the reciprocating screw is controlled by a driving assembly. A telescopic spring is sleeved on the insert rod, and the two ends of the telescopic spring are fixedly connected to the vertical plate and the body, respectively.

[0007] The surface of the movable ring is circumferentially fixedly equipped with multiple L-shaped rods, and the surface of each L-shaped rod is fixedly equipped with a stop rod. The surface of the inclined plate has openings for multiple stop rods to pass through. The opening wall of each opening has a horizontally opening for rotation. A rotating shaft is horizontally rotatably installed inside the rotating shaft. A rotating plate is fixedly sleeved on the rotating shaft. A mounting block is fixedly installed at one end of the rotating shaft. The mounting block is connected to the inclined plate through an elastic component. The rotating plate is restricted from rotating downwards by a rotation limiting component.

[0008] Preferably, the limiting component includes a limiting rod that is vertically fixedly installed on the upper surface of the device body, and the movable ring is slidably sleeved on the limiting rod.

[0009] Preferably, the drive assembly includes a drive motor, which is connected to the device body via a mounting component, and the output shaft of the drive motor is fixedly connected to a reciprocating lead screw.

[0010] Preferably, the mounting component includes a fixing ring fixedly sleeved on the drive motor and a support rod fixedly mounted on the outer ring wall of the fixing ring, wherein the end of the support rod away from the fixing ring is fixedly connected to the upper surface of the device body.

[0011] Preferably, the elastic component includes a torsion spring sleeved on the rotating shaft, with both ends of the torsion spring fixedly connected to the mounting block and the inclined plate, respectively.

[0012] Preferably, the rotation limiting component includes a rotation limiting plate, which is fixedly installed on the side of the rotating plate away from the rotating shaft. The upper surface of the inclined plate has a limiting opening, and the lower surface of the rotation limiting plate abuts against the wall of the limiting opening.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By coordinating the reciprocating screw, moving ring, insert rod, inclined plate, stop rod, and rotating plate, multiple vibrating balls can be controlled to intermittently collide with the surface of the bag, thereby effectively shaking off the dust adhering to the surface of the bag and preventing excessive dust from affecting the breathability of the bag.

[0025] Reference Figures 1-7 A high-efficiency vibrating bag filter includes a body 1. A filter bag 2 is fixedly installed on the top wall of the body 1. During normal operation, dust-laden gas passes through the filter bag 2, and dust is intercepted on the outer surface of the filter bag 2, with some adhering to it. The surface of the body 1 has multiple circumferentially openings 3. Insert rods 4 are slidably inserted into the openings 3. One end of the insert rod 4 is fixedly fitted with a vibrating ball 5 via a connecting rod, and the other end is fixedly fitted with a vertical plate 15. A slanted plate 6 is fixedly installed at the top of the vertical plate 15. A reciprocating screw 7 is vertically fixedly installed on the upper surface of the body 1. A moving ring 8 is threaded onto the reciprocating screw 7. The moving ring 8 is restricted from rotation by a limiting component, which includes... A limiting rod 16 is vertically fixedly installed on the upper surface of the device body 1. A moving ring 8 is slidably sleeved on the limiting rod 16. A reciprocating screw 7 is controlled to rotate by a drive assembly. The drive assembly includes a drive motor 17. The drive motor 17 is connected to the device body 1 through a mounting component, and the output shaft of the drive motor 17 is fixedly connected to the reciprocating screw 7. The mounting component includes a fixing ring 18 fixedly sleeved on the drive motor 17 and a support rod 19 fixedly installed on the outer ring wall of the fixing ring 18. One end of the support rod 19 away from the fixing ring 18 is fixedly connected to the upper surface of the device body 1. A telescopic spring 14 is sleeved on the insertion rod 4. The two ends of the telescopic spring 14 are fixedly connected to the vertical plate 15 and the device body 1, respectively.

[0026] Multiple L-shaped rods 9 are fixedly installed on the circumferential surface of the moving ring 8. Abutment rods 10 are fixedly installed on the surface of the L-shaped rods 9. The surface of the inclined plate 6 has openings 11, which are used for the passage of multiple abutment rods 10. A rotating opening is horizontally opened on the wall of the opening 11. A rotating shaft 12 is horizontally rotatably installed inside the rotating opening. A rotating plate 13 is fixedly sleeved on the rotating shaft 12. A mounting block is fixedly installed at one end of the rotating shaft 12. The mounting block is connected to the inclined plate 6 through an elastic component. The elastic component includes a torsion spring 20 sleeved on the rotating shaft 12. The two ends of the torsion spring 20 are fixedly connected to the mounting block and the inclined plate 6, respectively. The rotating plate 13 is restricted to rotate downward by a rotation limiting component. The rotation limiting component includes a rotation limiting plate 21, which is fixedly installed on the side of the rotating plate 13 away from the rotating shaft 12. A limiting opening 22 is opened on the upper surface of the inclined plate 6. The lower surface of the rotation limiting plate 21 abuts against the opening wall of the limiting opening 22.

[0027] Under the elastic potential energy of the torsion spring 20, the rotating plate 13 is initially positioned inside the opening 11, while the lower surface of the limiting plate 21 abuts against the wall of the limiting opening 22. When a downward force is applied to the rotating plate 13, it cannot rotate downwards. However, when an upward force is applied to the rotating plate 13, it will rotate upwards. Under the elastic potential energy of the telescopic spring 14, the vibrating ball 5 initially abuts against the surface of the cloth bag 2. In the initial state, multiple rotating plates 13 correspond to the positions of multiple abutment rods 10.

[0028] When the drive motor 17 is started, the output shaft of the drive motor 17 rotates the reciprocating screw 7. The moving ring 8, which is threaded onto the reciprocating screw 7, moves vertically back and forth under the restriction of the limiting rod 16. During the movement, multiple abutment rods 10 also move together. As the multiple abutment rods 10 move downward, they will abut against the upper surfaces of multiple rotating plates 13. Since the rotating plates 13 cannot rotate downward, the abutment rods 10 will slide down the inclined plane of the rotating plate 13 to the inclined plane 6. At this time, under the pressure of the inclined plane, multiple insertion rods 4 will move away from the bag 2. At this time, multiple vibrating balls 5 will no longer contact the bag 2, and the telescopic spring 14 will also be stretched. Then, when the abutment rods 10 move down to no longer contact the inclined plane 6, the pressure force exerted by the abutment rods 10 on the inclined plane 6 disappears. The insertion rods 4 will then move and reset quickly with the inclined plane 6 and the vibrating balls 5 under the elastic potential energy of the telescopic spring 14. The vibrating balls 5 will collide with the surface of the bag 2.

[0029] After being reset, the multiple rotating plates 13 will be located directly above the multiple abutment rods 10. Then, as the abutment rods 10 move upward, their surfaces will abut against the lower surfaces of the rotating plates 13 located above them. Under the pressure, the rotating plates 13 will rotate upward, and the rotation limiting plate 21 will move out of the limiting port 22. After the abutment rods 10 no longer abut against the rotating plates 13, the rotating plates 13 will quickly rotate and reset under the elastic potential energy of the torsion spring 20, and the rotation limiting plate 21 will rotate back into the limiting port 22.

[0030] As the lever 10 moves vertically back and forth, multiple vibrating balls 5 will intermittently collide with the surface of the bag 2. When the vibrating balls 5 intermittently hit the bag 2, the bag 2 will suddenly receive an external force and start to move. However, the dust particles themselves have the inertial property of maintaining their original stationary state. As the motion state of the bag 2 changes, and the dust particles want to maintain their original stationary tendency, the dust particles will have a relative displacement with the surface of the bag 2, and then detach from the surface of the bag 2 and fall down under the action of gravity.

[0031] The impact of the vibrating ball 5 will cause the cloth bag 2 to vibrate. This vibration will be transmitted in all directions along the cloth bag 2. Under the continuous action of vibration, the original tight bond between the particles on the surface of the cloth bag 2 will be broken and become loose. Once the dust particles are loosened, they are more likely to slide or fall off the surface of the cloth bag 2 under their own weight and the small displacement generated by the subsequent vibration, and eventually detach from the cloth bag 2.

[0032] The vibrating ball 5 impacts intermittently. Multiple impacts will have a cumulative effect. The first impact may only loosen and remove some dust, but subsequent impacts will continue to disrupt the dust's adhesion, causing more dust that was originally attached to the surface of the cloth bag 2 to be shaken off.

[0033] In this invention, the reciprocating screw 7 is rotated by the drive assembly. At this time, the moving ring 8 threaded onto the reciprocating screw 7 will move vertically back and forth with multiple L-shaped rods 9 and multiple abutment rods 10 under the restriction of the limiting component. When the multiple abutment rods 10 are moving, multiple vibrating balls 5 can intermittently collide with the surface of the bag 2 under the cooperation of the inclined plate 6, rotating plate 13, telescopic spring 14, elastic component and rotation limiting component, thereby effectively shaking off the dust attached to the surface of the bag 2 and avoiding excessive dust accumulation that affects the breathability of the bag 2.

[0034] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
